Abstract
A series of alternating copolymers of 2,5-(3,4-ethylenedioxy)thiophene and 1,2-vinylene with well defined repeat unit ratios were synthesize d and characterized electrochemically and spectroscopically. By increa sing the vinylene to thiophene ratio from 0:1 to 0.5:1 to 1:1 along th e polymer backbone, time bandgap of tile resulting polymers were reduc ed systematically as clearly evidenced by absorption spectroscopy. The 1:1 copolymer exhibited an onset bandgap of 1.0 eV.
